Can someone please help me? I really need it. And 10 points too best?

Well, me and this one girl really like each other. And we are both sopres in highschool. She is really pesimistic and stuff cause her parents do not treat her well, and offer her no religous tolerance, going against her faith. She has wanted to leave for a couple of years, but wanted a thorough plan, not just a run away and hope for the best deal. She and this one 18 year old had also been infatuated, and he moved to Canada, where he was recruited by a gang. He said he would help her, but has not come through for her because he does he has done some bad things, including murder, and does not want her to get hurt. She began dating me a while back, and I had helped her at home, been kind and caring towards her, and helped her a lot. Well, I had learned about this from many others, and then the bird sang herself. She said that she had had this happen before, but through some other events, never this far. She was crying by then.She said she was done with him, and was just going to force him out of her life. I told her that if she was serious, I'd stay with her and help her through this. Recently, I found out that this guy had tried to commit suicide last time she considered leaving him. He may be a bad guy, but he only kept her away to help her. Now I feel like the reason he could possibly be killing himself. I would never accept that. I told her that I'd stick with her through this, because I really care for her, but I can't stop it without someone getting hurt. I just want the solution that causes everyone as little pain as possible, keeps me her, and I guess him safe, and just stops all the tension. I am really confused, so please take this seriously and please try to help. And if possible, I want her to stay, and maybe try to get her parents to see the light and let her be who she is.
